Lower Nossob is an extinct Khoisan language once spoken along the Nossob River on the border of South Africa and Botswana, near Namibia. It was closely related to the Taa language.
There are two attested dialects: ǀʼAuni (pronounced), or ǀʼAuo, recorded by Dorothea Bleek, and ǀHaasi, recorded by Robert Story. ǀʼAuni is the word they formerly used for themselves; ǀʼAuo (or ǀʼAu) is what they called their language. ǀauni, ǁauni, Auni are misspellings. Other renderings of the name ǀHaasi are Kʼuǀha꞉si, Kiǀhasi, and Kiǀhazi.[2]
Güldemann (2017) lists the following doculects as being Lower Nossob.[3]
